CME livestock market funds that track the Standard & Poor's Goldman Sachs Commodity Index at times sold, or "rolled", August futures and simultaneously bought October on the fourth of five days of the Goldman Roll process.

August ended 0.450 cent per pound lower at 117.425 cents. October closed unchanged at 117.825 cents. December finished down 0.100 cent to 118.225 cents.

On Friday CME live cattle futures will resume their normal 3.000-cent price limit after failing to settle up or down the expanded 4.500-cent limit on Thursday.

Futures' bullish discounts to cash prices versus bearish wholesale beef values made it difficult to trade the market on Thursday, said Oak Investment Group President Joe Ocrant.

So far this week packers in the U.S. Plains paid $120 per cwt for slaughter-ready, or cash, cattle that a week ago brought $117 to $119, said feedlot sources.

They said feedlots are asking more than $120 per cwt for unsold cattle, given slipping but still profitable packer profits.

However, processors are aware that people typically grill less in extremely hot weather, which has dragged down wholesale beef values in recent weeks.

August feeders ended 1.275 cents per pound higher at 153.025 cents. Feeder cattle future will return to their usual 4.500-cent limit on Friday after not finishing up or down Thursday's 6.750-cent expanded limit. HOG

Futures End Mostly Firmer

Most CME lean hog trading months benefited from their discounts to the exchange's hog index for July 11 at 92.75 cents.

The roll by funds weighed on August futures and propped up the October contract.

July, which will expire on Monday, ended up 0.175 cent per pound to 92.750 cents. Most actively-traded August finished down 0.100 cent to 82.525 cents, and October ended up 0.050 cent to 69.325 cents.

Tight hog supplies underpinned cash prices, while retailers consider featuring beef that is now more competitively-priced to pork, said traders and analysts.
